Something cool I found, but takes a lot of patience and proper timing.

Step One: Go to Bianco Hills, Mission Six "Secret of the Dirty Lake" and go into the cave.

Step Two: Head to the yellow platform with those red triangles that appear out of nowhere and fly across the platform.

Step Three: This requires EXACT timing. Go onto the rotating cube that goes upward and go as high as you need (I'd say around halfway to the top) and when a triangle disappears, jump down and ground pound toward the platform. If you timed correctly, a red triangle should have appeared and flew across. If your ground-pound is near the triangle, for an odd reason, your ground-pound will instantly home in to the triangle instead of going in a straight fall.

Step Four: Go "What the heck?!"

And that's pretty much it. I'll see if I can find any other areas where this can be done.
